Concept introduction:
A complex ion is formed when a metal ion reacts with a Lewis base in solution. This reaction is defined in terms of
Metal ion which is positively charged functions as a Lewis acid. Lewis base or the ligandhas one or more lone pairs of electrons. For example, Cu2+,which is a highly charged and small metal ion having themajor tendency to function as Lewis acids, consequentlyexhibiting the greatest affinity to form complex ions.
(b)
Interpretation:
Equations which represent the given observation that when chromium metal is dissolved in HCl(aq), a blue solution is obtained which quickly turns into green color. After that, the green solution becomes blue-green and then violet should be determined.
Concept introduction:
A complex ion is formed when a metal ion reacts with a Lewis base in solution. This reaction is defined in terms of chemical equilibrium. A complexion comprises of a ligand and a metal ion as a result of an interaction of Lewis acid-base.
Metal ion which is positively charged functions as a Lewis acid. Lewis base or the ligand has one or more lone pairs of electrons. For example, Cu2+, which is a highly charged and small metal ion having the major tendency to function as Lewis acids, consequently exhibiting the greatest affinity to form complex ions.
